摘要

Summary. Enolacetates of benzocyclanones and chromanones were synthesized and treated with dimethyldioxirane and the asymmetric oxidizing system dimethyldioxirane/chiral , non-racemic Mn (III) salen complex/axial ligand. The latter reagent resulted in the corresponding enantiomerically enriched cyclic α-hydroxy ketones and their acetates in moderate-to-good yields and modest enantioselectivity under mild and neutral conditions ...
